Testosterone levels may play opposite roles in how older men and women experience suicide risk during severe depression. A new study finds that higher testosterone protects older men, but is linked to increased risk for older women.

Women experiencing a chronic lack of sexual desire still routinely engage in sexual activity to maintain relationship stability. A review of clinical trial data quantifies exactly how often this obligatory intimacy occurs and explores the psychological reasons behind it.

Men whose testosterone levels fall unusually high or low for their age group face an increased risk of developing depression. A large study suggests that midlife is a particularly vulnerable period for these hormone-related mental health risks.

A recent study provides evidence that administering opposite-sex hormones to rats shifts their sexual behavior to resemble the opposite sex. The findings suggest that these hormonal changes also suppress natural reproductive functioning.

New research reveals that adolescent boys hospitalized with major depression have much higher testosterone levels if they experience suicidal thoughts. The findings point toward potential biological markers that could help doctors identify young men at risk of self-harm.

A new genetic study suggests that the biological roots of depression and testosterone regulation are intertwined. Researchers found that specific genomic variances influence both hormone levels and the risk of developing major depressive disorder.
